installed by the Customer)
The control board of the Energy Plus units is
designed to receive a 0-10 V signal from a
CO
sensor. The characteristics of the sensor
2
that can be connected are:
- Recommended operating range: 0-2000
ppm
- Signal output: 0-10 V
The Customer shall set up the sensor power
supply according to the specifications of
the selected product. It is usually a power
supply with these specifications:
- 24 V AC
- 15-35 V DC.

CONDENSATE DRAIN
SIPHON
The unit has a condensate drain at the
bottom to which must be fixed a siphon which
can ensure the efficient draining of water
during normal operation.
The siphon must always meet the fol-
lowing specifications and the discharge
pipe have to be at a minimum gradient
of 3°.
The siphon is essential for correct operation
of the energy recovery unit as it prevents
the infiltration of air and yet ensures the
natural flow of the condensate. The siphon
must be filled with water and sized according
to the function to prevent that the air in the
discharge system will be drawn by the heat
recovery unit and doing so obstructs the
proper drainage of the condensate.
The system must be pressurised as follows:
H1 = 2P
H2 = H1 /2
Where P = max operating pressure of the
heat recovery unit in mm, approx (1 mm
approx = 9,81 Pa).
